CHARLES O. K. HALGREN, OF BAYONNE, NEWV JERSEY.

BOX-OPENER.

SPECIFIOATION forming part Of Letters Patent N0. 678,780, dated July 16, 1 901. Application filed August 8, 1900. Serial No. 26,235. (No model.)

To (LZZ whom it may concern:

Be it known that I, CHARLES O. K. HAL- GREN, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Box-Openers, of which the following is a specification.

One object of my invention is to provide a machine for removing the tops or covers of boxes,especiall y those boxes such as surround glass car-boys and which tops are made in one or more wide single pieces of lumber, which are very expensive.

The principal object of my invention is to produce a device by which these can be removed expeditiously and without injury.

In the drawings forming part of this specification, Figure 1 is a front elevation of my machine. Fig. 2 is ahorizontalsection taken on the line 1 1 of Fig. 3, parts of the lower structure being broken away and removed. Fig. 3 is a vertical central section, parts being left in elevation. .Fig. iis a section showing the jaws and means for operating the same, parts being shown in elevation. Fig. 5 is a detail showing the casting to which the upper one of the jaws is secured.

The main frame of the machine consists of side pieces A, joined by a cross-piece B at the top and having a suitable platform at the bottom. On this platform are placed a series of rollers D, along which the box may be easily slid, and in front of the platform is a turn-table E, so that the box may be easily turned into position to slide into the machine. On the rear part of the frame is an adjustable gage or stop F, which may be of any construction, but which being indicated in the views of the drawings requires no detailed description. Running centrally through the upper cross-bar is a rod G, which is pivot- This vertical rod passes through the cross-piece at the top of the frame and also through a crossbar J, forming the upper part of the frame, which is composed of said cross-bar J, a lower cross-bar K, and side pieces L. This frame is so constructed as to be capable of movement up and down independently of the rest of the structure. Suspended from the crossbar I are vertical hangers M, at the lower ends of which are carried the jaws N N, the lower jaw N being attached by bolts to the sides of the hangers M, as clearly indicated in Fig. 4:. Sliding between the sides of the hanger M is a casting of the shape shown in Fig. 5, which consists of a vertical part 0, provided with grooves P, which engage the sides of the hanger, and a horizontal piece Q, to which piece the upper jaw N is secured by bolts, as clearly shown in Fig. 1. The lower bar K of the movable frame passes through the upper part of the vertical piece O. Through the lower part of'this casting runs the shaft R, which is provided at its center with right and left hand'threads S. This shaft is free to rise and fall in the frame of the machine. Attached to the casting of the upper jaw are brackets T, at the ends of which are secured nuts U, threaded to fit the screw-threads on the shaft. The shaft is provided with an operating-handle V. The hangers M are provided at their upper parts with antifriction-rollers XV. Attached to the rod G at its upper end is an operating-lever X, which is provided with a ratchet-stop of any desired form, the rod being pivoted at the point Y to the upper part of the frame of the machine. The lowerjaw N is made considerably wider than the upper, and to avoid complicating the drawings only one of said jaws is indicated to its full length. This lowerjaw is made substantially of the width of the widest box which it is intended to uncover with the machine.

Pivotally attached to the vertical rod G is a lever a, which has at one end a handle, and pivotally attached to the other end a link I), which at the lower end is connected with the cross-bar K. The operation of the device is as follows: By manipulating the adjusting-handle X it will be seen that the entire apparatus, com posed of the frame, the cross-bar I, hangers, jaws, and operating-rod, will be raised or lowered, thus making it possible to accommodate the device to boxes of different heights. This adjustment being made, a box is placed on the turn-table E and turned so as to be in proper position to enter the machine. The box is then shoved over the rollers, bringing up against the stop F, being then in position to have the first part removed from the cover. Operating the shaft R by its hand-wheel V regulated that. the lower jaw operates against the sides of the box, while the upper jaw engages in the space between the cover and the 'upper edge of the box, as clearly indicated in Fig. 1, where a corner of a box in position is shown. By pressing down on the lever a the'sliding frame rises, carrying with it the upper jaws N and the screw-shaft, the result of which will be to remove the cover from the box.

The upper jaws are withdrawn from underneath the cover by manipulating the screw shaft, and the cover is removed bodily. The upper jaw is then lowered by releasing pressure on the lever CL, the box moved forward to its proper position, and the next section of the cover removed in the same manner.

The stop or gage described and shown may of course be omitted or may be placed in any convenient place- 7 It will be obvious that if desired the'jaws may be made in one piece to engage and lift the cover, the box being held down either by its weight or by extraneous means.

What I claim, and desire to secure by Letters Patent, is-

1. The combination in a machine for removing covers from boxes of jaws, of mechanism for causing the jaws to engage the cover of the box at each end, and mechanism for moving said jaws upward, whereby the cover will be bodily removed, substantially as described.

2. The combination in a machine for removing covers from boxes of jaws, of mechanism for moving said jaws horizontally to engage the cover of the box at each end, and mechanism for moving said jaws vertically, whereby the cover will be bodily removed, substantially as described.

3. In a machine for removing covers from boxes, the combination of a pair of jaws each made in two parts, one to bear against the box and one to engage the cover, means for adjusting them to the box, and means for giving that part of the jaw engaging the cover an independent upward movement, substantially as described.

4. In a machine for removing covers from boxes, the combination of two sets of jaws, each set being made in two parts, means for moving the same horizontally and vertically, and means for giving the upper parts of the jaws independent upward movement, substantially as described.

5. In a machine for removing covers from boxes, the combination of jaws, means for moving the same horizontally and vertically whereby they may be made to engage the cover and lift the same from the box, and means for adjusting themechanism for boxes of difierent heights, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at New York, in the county of New York and State of New York, this 6th day of August, 1900.

CHARLES O. K. HALGREN.
